LM4041DIM3X-1.2 from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CATHODE | passive | Cathode. Shunt current flows into this pin and it develops the +1.225 V reference voltage relative to the anode. Operating current range 60 µA to 12 mA; maximum reverse current 20 mA (absolute max). |
| 2 | ANODE | passive | Anode pin, normally grounded. Return path for the shunt reference current; forms the negative reference terminal. |
| 3 | NC | unconnected | No internal connection. Must be left floating or tied to the ANODE pin (per datasheet note **). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 502 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
